Effects Of Different Soil And Different Soil Water Content On Photosynthetic Characterristics And Growth Of Panax Ginseng

The ginseng for the perennial herb shade plant, is Jilin Province unique and the big area introduction cultivation planter precious traditional Chinese medicine. Its output is low, the vegetative cycle long has been limits the ginseng production the key aspect. In order to expound the suitable ginseng grows the soil moisture content, is the high production cultivation practice provides the theory basis, with the American CL-340 portable photosynthesis meter, the TSC-1 moisture content tachometer, and unify the conventional physiology biochemistry parsing technique. To the annual, triennial ginseng various periods of duration the growth target,Fast-growing time photosynthesis,enzyme activity,MDA content, soluble sugar,protein content and soap glucoside content have conducted the quite systematic research. The main result is as follows:To determines the ginseng different time high, the stem to be thick, the chlorophyll, the petiole are long, the root heavy and so on growth targets and the economic indicator, the research different soil type, the soil moisture content the influence which grows to the ginseng. Soil moisture content's increase, the ginseng each growth target enhances, the farmland soil plants the ginseng growing trend is weakest, the farmland earth and the humus soil are highest according to 1:3 mix's ginseng each growth target.Ginseng photosynthesis's each target increases along with the soil moisture content increases. The humus soil content increases also makes the photosynthesis each target to increase. The annual, triennial stranger announce candidacy selects has representative exhibition Ye Qi, the green fruit time to determine its photosynthesis each target, the annual and triennial stranger aberration tendency is the same. The intercellular CO₂ density diurnalvariation rule with photosynthesizes the speed change to be basically opposite only.The different soil and the different water content to the ginseng leaf blade MDA content, and the soluble sugar, the protein content are influential. In forces under the condition, the MDA content, the enzyme activity can play the protective function.The different soil moisture content has the obvious influence to the ginseng total soap glucoside content. The suitable moisture content is advantageous to ginseng root expanding and the soap glucoside accumulation.The result indicated: Plants the ginseng with the farmland soil, The large Chinese hawthorn the soil moisture content should control ahead of time in 80%; Plants the ginseng when with the farmland soil and the humus soil mix soil, is withering the soil moisture content to control ahead of time in 80%; Ginseng which plant with the farmland earth and the humus soil mix, regardless of the aerial parts grow the underground spot growth to surpass the farmland soil to process, but humus soil high content of the best.
